Solving the case is a little bitter, but my sister is super sweet

"After Cheng Gao went abroad, our people monitored him every now and then and discovered something."

"Cheng Gaogao has a close relationship with a female graduate student from Kimchi Country... What I mean by closeness is that it only took three days for them to go from strangers to familiarity to booking a hotel room."

"For the next four months, they were like a couple...but a week before Cheng Gao returned to China, they had a quarrel and broke up."

"Originally, this kind of thing seemed normal, but now I think about it carefully. Two graduate students were able to check out a room within three days of knowing each other. This in itself is a small problem, but it is not a big problem."

"Because after Cheng Gao returned to China, our people continued to follow him in prison for a period of time. We did not discover that Cheng Gao was engaged in espionage activities, nor did we have the opportunity to leak important secrets."

"Now that you are making this call, I don't need to ask what it is about, and I know that there is something wrong with Cheng Gao, and the Tenth Bureau also gave a message that his tutor is a very powerful professor."

Shen Yongjun’s voice was cold, “Wang Liangxu, received his bachelor’s degree in 1982, his doctorate in 1989, engaged in postdoctoral research from 1989 to 1991, taught at the University of Michigan from 1992 to 2007, and taught at Seoul National University from 2008 to 2013, and was hired as the Distinguished professor of the school. In 2014, he returned to China and was appointed as a chair professor of molecular cell biology by the Chinese University of Science and Technology in City C. He is a senior researcher in the XX laboratory and focuses on virus survival and evolution mechanisms, evolutionary biology, genetic mutation... virology! "

Virology... Lin Xuan's face was as cold as ice.

Found the rightful owner!

Because there has never been such a coincidence in the world.

Six victims died of the virus, the virus was found, and now the professor was found.

Another point.

This Wang Liangxu stayed in Kimchi Country for five years, and the suspect Cheng Gaogao also went to Kimchi Country.

Now Wang Liangxu is Cheng Gao's mentor again. Let's talk about coincidence. Whose IQ is it insulting?

"Do you want to investigate Wang Liangxu?"

Shen Yongjun suddenly said: "I have some bad news for you. Wang Liangxu disappeared three months ago. The National Security Bureau has investigated it and found out whether he was alive or dead!"

Lin Xuan:......

What a coincidence, what a coincidence!

After ending the call, he rubbed his eyebrows with a headache.

Everyone checked by the National Security Bureau was confirmed missing.

Any hope of finding it?

Two words: slim!

But no matter how slim it is, you have to find it.

One day passed in the blink of an eye.

The investigation on Wang Liangxu was fruitless!

…

Inside the hotel.

Lin Xuan, who had not rested for three days, lay in bed unable to sleep.

He was forcing his brain to calm down, making his thoughts clear, and starting the most rigorous reasoning.

An hour passed.

Suddenly, Lin Xuan's pupils shrank.

This case... is wrong!

First of all, there are six corpses in three cases, which does not look like some kind of human experiment at all.

It was most likely intentional homicide.

As for murder, as long as it is not insane, there must be a reason.

After investigation.

There is no cause and effect between the six deceased persons.

They have a high relationship with the suspect and have no causal relationship.

Assuming that Cheng Gao planned the poisoning, was it just to kill people randomly?

What good does this do him?

Or are you unhappy with your life and want to take revenge on society?

neither.

After investigation, it was found that Cheng Gao's family was very good. His parents had some assets. Although he was not the second generation, he was not short of money to spend.

And he has a good rapport with women. He had two girlfriends in college, and even hooked up with a graduate student in Kimchi Country.

In terms of academic research, everything goes smoothly and satisfactorily.

Such a person has no reason to go to extremes.

There is no reason to poison others.

There is another key point.

Where did his virus come from?

Not to belittle him, but he might not be able to research that kind of terrifying murderous virus.

It should be a large experimental institution to be able to research such a terrifying thing.

So, is it possible that the virus in Cheng Gao's hands came from a large laboratory?

If so, go back to the original question.

Why do people poison and kill people randomly when the cost is high?

Lin Xuan's mind was boiling, and he also opened up his imagination.

All kinds of information and possibilities converge in the brain.

Reasoning over and over again, pondering over and over again, reviewing again and again.

Sudden.

Lin Xuan's eyes suddenly flashed with light, and he quickly took out his mobile phone.

Called Wang Meng and Zhou Lie.

He said to them: "Check, Cheng Gao entered three supermarkets and saw if there were any suspicious people around him!"

Three hours passed in the blink of an eye.

Zhou Lie called, "A suspicious person was found. Because it was monitored by City Skynet, this person could only be identified twice. Each time, the cost was high. After entering the supermarket, the suspect appeared outside the supermarket. But because The other person is wearing a mask, hat, and sunglasses, and his age and gender cannot be confirmed, but judging from his body shape, he is most likely a woman!”

Oh... A smile appeared on Xuan Fang's face, "Find her!"

Put down the phone and keep thinking.

If this is the case.

Is it possible to deduce that someone is always monitoring Cheng Gao?

Or not just monitoring, but a kind of... control?

Is the high cost controlled by someone or an organization?

Is it possible that his murder was a kind of... self-saving?

Kill to save yourself?

Only Lin Xuan could come up with this kind of idea.

Then even if he was rescued, he would still die?

No, not necessarily.

If his purpose of killing was to save more people, he would not die, and he might even be... innocent!

It's like a high-speed train that can't be stopped.

The train is full of passengers.

The track changes ahead, and it is divided into two lanes.

In one lane, there are ten people tied up.

At the end of one lane... it will derail.

You have a remote control button in your hand that can control the train to change tracks.

Now you have two choices.

1. Let the train run over those ten people to save your life and the lives of everyone on the train.

2. You can choose to derail the train, save the lives of those ten people, and you and everyone on the train will be destroyed.

Normal people, don't they already have a choice?

Don't say that you have no right to deprive others of their lives.

Under this premise, you must first survive.

Secondly, consider whether those ten people will die or everyone on the train will die.

Is this the truth?

Why did Lin Xuan think of this?

Virus!

Is it possible that the virus will appear in the entire C city?

Or will it be used on all Dragon people?

Everyone is about to face a life-and-death crisis?

The reason why Cheng Gaoang used such a horrific method to kill people was to attract the attention of the police, or to attract more powerful people to appear.

Find him, find the virus, in order to save more people?
